btw, you can patch the problem yourself in the meantime by adding a line
to backend/parser/gram.y:
1) in an editor, look for the line starting with "ColId"
(near line # 4639)
2) add a line in the block of code immediately following the "ColId"
which references "timestamp" in the same way that the other lines
reference those reserved words.
3) re-install the backend (you must have bison available on your system
to rebuild the gram.y).
